It was difficult to find out which powerpoint to pick but I chose the Jeopardy one because it was fun and very easy to learn. Some of the other ones were from highschool but I believe this was an 8th grade presentation. The information was accurate and factitious. All of them had a great amount of truthful facts but some were to advanced.
